Abstract
The present invention addresses the problem of simplifying the provision of microwave lenses in particular, but not exclusively, when microwave lenses are disposed in the close proximity of antenna elements ( ) in devices ( ) for transmitting and/or receiving microwave radiation. According to the invention, a microwave lens is formed from a droplet ( ) of material that refract microwave radiation. The droplet ( ) assumes a predetermined shape in a liquid state, said shape depending chiefly on external limitations, the volume of material used and the properties of the material. The droplet ( ) is then allowed to solidify while retaining said assumed shape. The invention relates to devices and methods relating to this simplified provision of microwave lenses.
